Question

Solve each linear system. Verify each solution by substituting the coordinates of your solutino into both equations.

a) y = -x and y = x - 6
b) x - y = 8 and x + 2y = 2

Answer 1

well, do what they said
y = x - 6
but they said y = -x
so
-x = x-6
6 = 2 x
x = 3

in the next one
y = (x-8)
use that in the second equation
